John Denver Tribute for Wilderness with John Fielder

John Denver Tribute for Wilderness with John Fielder and the John Adams band

Celebrate the 50th anniversary of the passage of the Wilderness Act and support Sierra Club RMC endeavors at this momentous event. See 1,000 awe-inspiring John Fielder photographs (some never seen before) from over 40 years of his American wilderness collection projected on a 30-foot high screen choreographed to the great, timeless music of John Denver as performed by the incomparable John Adams Band. Enjoy it all while comfortably seated in Denver’s elegant, crown jewel performance hall, the Buell Theater.
